Mortland was a member of the Society of the Friends of the People, a Whiggish organization which advocated for Parliamentary reform and universal suffrage. He attended the first general convention of the Scottish Friends of the People in Edinburgh in December 1792. He was however a prosecution witness in the August 1793 trial of Thomas Muir of Huntershill for sedition.

Mortland was one of the founders of the Scots Chronicle newspaper in 1796. The Chronicle opposed the war on France, and Mortland was sued for libel over a letter published in the paper.

Rindmuir House was renamed Rhinmuir House and was successively the home of the Pollok family and from 1901 the Kerr family. It was burnt down in 1995. It lay in the Easterhouse district of Glasgow. His Edinburgh house at Queen Street was later the home of the surgeon James Dunsmure.
